COVERING FOR HANG-LE -ROLLS.

Specification of Letters Patent.

Patented Oct. 29, .1907

To all whom it may coricem:

Be it known thatI, .Lmss H. Hour, of Greenwich, in the county ofFsirfield and State of Connecticut, have invented certain new and usefulImprovements in Coverings for Mangle-Rolls, of which the following isaspecification.

This invention relates to certain new and useful improvements incoverings for mangle rolls, and the object of my invention is to providea new and elastic covering which is exceedingly durable and is so helddesired c'pshioning effect may he produced.

The covering for mangle rolls as now generally used in large factoriesfor the manufacture of shirts, collars, cuffs, and the like, has to berenewed about five times intern on account of the hardening of thefibers and the consequent loss of the cushioning effect so necessary toturn out good work. In addition to this hardening effect, since thecoverings of the mangle rolls are in peripheral contact witha highlyheated revoluble cylinder, the intense heat, together with the pressureto which the fibers of the covering are subjected, scorches the fibersof the covering and at the some time renders them hard and stiff so thatthe rolls become gradually less efficient, and finally the renewal ofthe covering fiacomes' necessary at considerable expense and loss of meincident to the stopping of the triangle. I overcome these difficultiesby employing a, fireproofed felt covering which is of such a nature asto resist scorching and at the same time preserve its cushioning cffcci,notwithstanding thehigh heat and grout pressure, and

by winding the covering spirally in such it way that its 40 sod-.1,tungstste of soda, and water, and also to ugoiu treat the feltedmaterial with the same solution during, the last step of the fellingprocess. ()ihcr solnlions maybe employed with good effect, and 1 our notlicrciu claiming the method of lire-proofing, as I am aware that suchfire-proofing processes are old pcr sc, but I believe it is new to havea mangle roll covering of felt which is fire proofed, irrespective ofhow this fire proofing is accomplished, whether by chemicals orotherwise. After the material is felted and is iirc-prooied, it is cutin somewhat narrow widths with bcvcledndgcs and these strips are thenwound upon the rollers spirally. At each end of the roller I provide :1.slccvc or Collar to which the ends of the spirally wound strip areconnected. These slcevcs or collars are arranged so that they may befreely'rotated with respect to the roller but are provided with clampingscrews permit ting their position to be changed with rcspcci lo rhc oxlcor jourmils of the rollers in order that the propcr icusiou only begiven to tho covering so tlmi rhc ])r'i|]n'i'1*ll l|iHIi mu be produced.lulso dccm it advisable lboi rh covcrings not only have ilicir edgeslHYllOll N llllll tho ouc lightly overlaps the other, but it is ui o di'rublc to crowd llio covering onto the roll, and this i \'cr \wlleffected by means of the sleeves or collar .u'orcmil My inventiontherefore consists in thc muuglc roll covering hereinafter moreporticuhrrl; lltlll ildl in its preferable embodiment and theirdclinilcl) sci. forth by the claims at the end horcof.

In the accompanying drawings which rcprcscnl Lllv prcfcruble embodimentof my invention: i igurc l is J sectional view of part of a laundrymachine having various rollers showing the application of my ili\'cfltion. Fig. 2 is a side elevation, partly in scction, and Fig. .3 is aperspective View of a roller covered in accordance with my invention.

Referring now to the aforesaid drawings by reference letters; In Fig. 'lof my drawings is shown a machine, commonly known as a mangle in whichthe steam heated cylinder A is surrounded by a plurality of mangle rolls1), thcso last mentioned rolls being cov cred, where they come intoperipheral contact with I the aforesaid steam heated cylinder A, bymeans of a felted fabric B. ,This felted fabric is firc-proofcd by anydesirable means, but preferably by means of a solution consisting of tenpercent of silicate of soda, five percent of tungstate of soda, andeighty-five percent of water. After this covcring is iirc-proofcd, it iscut in a continuous strip of suitable width with the side edgesbevcledus indicated at b. This strip, with its beveled edges is thenwound upon the cylinder or mangle roll D, and to each end of this stripis secured one of tho collars dcsignated by the letter E, thcse collarsbeing capnblc of free rotation upon the shafts d of thc mangle rolls l)and yet are capable of being socurcd ihcrcto by means of clamping screwsc. These collars may he used to tighten the spiral winding 10 anydcsilcrl cxfcut, and then the clamping scrcws e um cmploycd to clamp thecollars E to thc shafts of the rolls. This providcs u covcring of.fcltcd lircproofed fabric which is hold upon thev rollcr at the propertonsion and this covering will be found cxcccdingly ellicicnt and oflasting quality thc lire-proofing preventing scorching and hardening andthe thick fclt--which is prcfcmblyfrom scvcn to nine sixtecuths of aninch in thicknessproviding a cushion which, bccause of the spiralwinding and adjusting collars, may he changed as desired. i

i am well aware that it is old to fire-proof various materials; and I amalso aware that it is old to wrap rollcrs with spirally wound matcrinl.Nevertheless I believe am the first to employ a l rc-proofcd fcltcovering for o. mangle roll and also that I am the first to eoerrm 1. loa machine of the character described, a roll having :1 covering o1iireqvrooied i'eli, said covering being spirally wound upon said roll,:lllil menus [or holding the some tin-rein Jil'ill winding comprisingone in r of sufficient iii '2 to form the (it-sired cushion,substantially inc ot the character described, a roll having :1tuiti'illg o1, iire-prooi'ed i'clr, slid coverinnbi-iug spirally woundupon sui i roll, means rerolubly supported with relat on iu the roll andits spiral winding r nd arranged to be ion with relfition thereto tochange the tension of the conning, in is also being arranged to be heldwith relation to tlr roll and covering, so, as to hold the letter at thetension (it ired, substantiiilly as described.
